Measurable Objectives:

Upon completion of this course, the student should be able to:
  1. use models to identify the structures of the teeth;
  2. identify tooth form and function, distinguishing major crown and root characteristics;
  3. communicate and apply the universal, palmer and FDI numbering systems;
  4. differentiate between deciduous and permanent dentitions;
  5. recognize early signs of deviation in deciduous, mixed and permanent dentitions;
  6. identify and discuss embryonic stages of tooth development and common dental anomalies found in the dentition;
  7. identify and communicate the major parts of a tooth;
  8. identify each of the five surfaces of a tooth and locate the point and line angles;
  9. apply principles of dental notation as it relates to restorative charting;
  10. identify and discuss the different embryonic periods of development;
  11. recognize and describe the different cellular structures of the oral cavity;
  12. describe different occlusal classifications;
  13. discuss the supporting structures found in the periodontium.
